Engineering 2019, Volume 5, Issue 2,   Pages 223-233 doi: 10.1016/j.eng.2018.11.021

Abstract:

A full-scale composite floor plate was tested to investigate the flexural behavior and in-plane effectsof the floor slab in a grillage of composite beams that reduces the tendency for longitudinal splittingof the concrete slab along the line of the primary beams.slab due to the restraining action of the floor plate, which was held in position by the peripheral compositebeams; while the secondary beams acted as transverse ties to resist the forces in the floor plate that

Abstract: ductility in this material and the quasi-brittle behavior of concrete, FRP-reinforced concrete (FRP-RC) beamsBecause the limited deformation capacity of FRP-RC beams depends on the ductility of their compressionA control beam and four beams with different PCCBs were cast and tested under four-point bending conditionsThe goal was to find an appropriate PCCB for use in the compression zone of the beams, which not onlyimproved the ductility but also changed the failure mode of the beams from shear to flexural.
